People say "When you're down you'll find out who's your real friend." I would say that you'll find it when you move abroad as well. In six days it'll be two months since I moved to the UK.
  After these two months I think I wasn't wrong about my best friends from Czech.We're in touch every day and we know about every little stupid thing which happens to each other :-).
Of course, I hope to find good friends also here.
In these days I'm happy for modern technologies and for the good old mail! It is amazing to get a letter from a friend who lives more than 1 000km away from you.
P.S: Success is the best revenge.
